To find the LCM of two numbers, you first split them into their prime factors: 30 = 2x3x5 75 = 3x5x5 Next you need to work out the HCF. Here, the HCF will be 3x5 = 15. Finally, you multiply the numbers together and divide by the HCF. 30x75/15 = 150. Therefore the LCM of 30 and 75 is 150.

In order to have a LCM of 30, the two numbers must only have unique primes that multiply to give 30. 30 is the product of 2, 3 and 5. To have an HCF of 2, the two numbers must only share a factor of 2. Thus the factors of one must be 2 and 3, and the factors of the other must be 2 and 5: 2x3 = 6 2x5 = 10 Therefore the two numbers with an HCF of 2 and an LCM of 30 are 6 and 10. or 2 and 30

5 and 30, respectively.

hcf(14, 30) = 2 lcm(14, 30) = 210 14 = 2 x 7 30 = 2 x 3 x 5 hcf = 2 lcm = 2 x 3 x 5 x 7 = 210

This will be difficult to answer correctly without the given number, but let's say the given number is 30. Two numbers with an LCM of 30 are 15 and 30, among others.

HCF of 3 means that the two numbers share 3 as a prime factor. LCM of 30 means there is a 2, a 3 and a 5 as prime factors between the numbers. With this info, we can have the combination where one number has a 2 and the other a 5 (and both have the 3) or one number has just the 3 and the other has 2, 3 and 5. Thus the 2 numbers can be 6 and 15. Or they can be 3 and 30.

In these types of problems, the numbers can also be the answer. 3 and 30 have a GCF of 3 and an LCM of 30. Since the product of the GCF and LCM of two numbers is the same as the product of the numbers, you could also use another factor pair of 90, like 6 and 15.

The HCF of the given two numbers is 6

6 and 60, respectively.

HCF is the highest common factor of two or more numbers. HCF of 20 and 30 is 10.

Not always, sometimes the LCM equals the greatest number, i.e.the LCM of 5 and 6 is 30, the LCM of 3 and 6 is 6.

The LCM is 30.

The GCF and LCM of 18 and 30 are 6 and 90, respectively.
